I may have mentioned that Neighbor D is, er, particular about when and how certain issues of maintenance are handled. He has 16 big Rolls Surrette batteries, (he needs all that because he runs at 48V for his 240V workshop tools,) each one costs three times what one of my new batteries does, and he’s not made of money.
When he was in the hospital 4-5 years ago he fretted about his batteries, which he lovingly services every two weeks, and … it’s not that they’re due, it’s that this is the day. So, because he really will worry about it, I went over and inspected and filled his batteries this morning.
That’s a nice box. The only one I know of locally with active venting. I’d have built it with a removable front because those things are heavy, but other than that it’s a joy to work with.
